Normal functions returning _Atomic doesn't compile either.


The C standard is poorly-written in this area, but I think it would be reasonable for CheckFunctionReturnType to just silently remove _Atomic.  (You will not be able to just re-use your new method there; removing other qualifiers is not acceptable, I'm afraid.)
